JAMES sT. EBERT, OF NEW ROCHELLE, NEW YORK.

AUTOMATIC'FUNNEL.

SPECIFICATION forming part 0f Letters Patent NO. 539,422, dated May 21,1895. y

Application dled December 29, 1894:. Serial No. 533,236. (No model.)

To @ZZ whom it may concern-.-

Be it known that l, JAMES J. EBERT, a citizen of the United States, anda resident of New- Kadapted for sealing theneck of a bottle while thesame is being filled; the objects of my'invention being to facilitatethe work of filling bottles or other similar vessels, and to preventoverfiow and vconsequent waste of liquid While the same a're beingfilled. I attain these objects by the mechanism illustrated in theaccompanying drawings, in Which- Figure l is a vertical section showingmy yimproved funnelfitted within the neck of a bottle. Fig. 2 is a sideelevation partly broken away. Fig. 3 is a sectional elevation of aportion of a funnel fitted within the neck of a bottle, showing aslightly-modified construction. Fig. 4 is a side 'elevation of a portionof a funnel, partlyin section, showing another modification. Fig. 5 is asectional elevation of a portion of a funnel, illustratinga furthermodification.

In the construction of my invention, an ordinary funnel bowl or body A,is provided at its lower or outletportion with a heavy metallic sleeveB, which slides vertically upon a funnel stem C. Within the said funnelstem O, and attached securely thereto is an air tube or vent D, throughwhich the air from a bottle v passes while the same is being filled.This said air tube terminates at its upper end above the top line of thefunnel bowl A, and at'its lower end at or near the bottom or outletportion of the said funnel stem C. rlhe said funnel stem C is alsoprovided with a stop c, adapted to rest upon the sleeve B, of the funnelbody A, when the funnel is lifted from the neck of a bottle. Fluid inletfrom the funnel body A to the stem C is effected by means of sleeve B,which rests thereon while a bottle is being iilled.

In the practice of' my invention, I prefer the construction as describedabove and illustrated in Figs. 1, 2, and 3, but it will be readily seenthat slight modifications in construction may sometimes be desirable; asforinstance, the bottle closing device E may be ade] ustably securedtothe stem C, as illustrated in Fig. 4, in which case, the latter isprovided with an exterior thread c2, and the former with a threaded andgrooved collar f, adapted to engage with the said thread and to receivethe bottlel closing device E.

In Fig. 5, a further modification is shown, in which the bottle closingdevice E is shown attached directly to the sleeve B, in which case, thestem C must be provided with a collar g, adapted to engage with the neckof a bottle being filled and to prevent the funnel stem from beingremoved from the body, should the same be inverted.

The operation of my invention is as follows: When the tube or stem C, isinserted within the neck of a bottle to a sufficient distance to allowthe bottle closing device E to come in contact with the upper portion ofthe said bottle neck and rest thereon, the funnel body A, and its sleeveB, will slide downwardly upon the stem C, until the sleeve B shall restupon the ilange e', of the bottle closing device E, thereby opening theiiuid inlet d, and sealing the neck of the bottle being filled, bybending the said dange e., of the bottle closing device E, over andaround the top portion of the bottle; whereby a perfectsealing of thebottle neck is effected without exerting any pressure upon the bottleclosing device E, other than that supplied by the oombined weight of thefunnel body, its contents and its sleeve B. The liquid is now allowedICO to flow with perfect freedom until it reaches a level on a line withthe lower end of the vent tube D, when further inflow is prevented bythe rising liquid closing the vent. The funnel is then removed from theneck of the bottle by the simple act of lifting the funnel body, whichslides upwardly upon the t stem C, until its sleeve B comes intoengagement with the stop c. The fluid inlet has now been completely shutoff, and no further outflow of liquid can be eected until the stem C isagain placed within the neck of a bottle. and the funnel body is allowedto drop and open the iuid inlet.

Theoperation as above described applies to the constructions as shown inFigs. 1, 2, 3, and 4, but it will be readily seen that my inventionapplies equally to the construction as shown in Fig. 5, whereby thesealing of the neck of a bottle is effected by the same means, viz: thepressingof the flange e', of ay bottle` closing` device around and overthe` neck of a bottle being filled.

It will be evident to those familiar with the art of filling bottlesthat my bottle closing device has advantages over any similar deviceheretofore used in combination with an automatic funnel; as by its use,I not only` eect a perfect sealing of the neck of a bottle, by bendingthe flange e over and around the neckof same, thereby covering anyindentations which may be accidently formed thereon, but I effect suchsealing by simply relying upon the pressure exerted by the weight of thefunnel body and its sleeve B, thereby obviating the necessity of tightlypressing` the bottle sealing device Within the neck of a bottle, wherebyinstantaneous removal of the funnel from the bottle is prevented by thebottle closing device adhering to the neck of the bottle.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. In an automatic funnel which comprises in its construction a bowl orbody adapted to slide vertically, upon its tube or stem, the combinationwith a pliable rubber ring mounted upon and projecting outwardly fromthe said tube or stem, of au annular projec tion upon the lower end ofthe funnel body, adapted to engage said ring and bend the same over andaround the neck of a bottle, substantially as shown and described.

, 2. A funnel tube having connected to it a vertically adjustable bottleclosing device, comprising a metallic collar having an annular grooveformed thereon, a fiexible ring, Sealed in said annular groove andhaving a flange formed integrally with said ring, combined with asliding funnel body, adapted to rest upon the flange ofthe said bottleclosing device, for causing the same to seal the neck of a bottle,substantially as shown and described.

3. A bottle closing device comprising a flexible ring having a flangeformed thereon, combined with a funnel tube having fluid inlet at itsupper part, and a sliding funnel body adapted to rest upon the saidbottle closing device, for causing the same to seal the neck of abottle, substantially as shown and dcscribed.

In testimouy that I claim the foregoing as my invention I have signed myname, in presence of two witnesses, this 19th day of December, 189i.
